No, go to the transport office in Phuket town and the process is the process full stop.
Due to how busy they were I had to do it in 2 visits and the total cost was 250 bht for both car and bike licences (2yrs).
First visit - Submit your paperwork, passport, licence, residency and medical certificate etc (2 x copies plus originals).
They give you some online links to view, which is around Thai driving laws etc. About an hour of your time at home and answer a couple of easy multiple choice questions. You will get a ‘pass’ message once completed. Keep that ready for your second visit.
Second visit - Do a simple break reaction test involving mock break and accelerator peddles. Also a colour blind test. All very easy. Pay your money, have your photo taken snd then wait for your licence to be printed.
Total time for both visits around 2.5 hrs.
